Understanding Spread Spectrum Communication Systems

Spread spectrum techniques involve spreading a signal over a wide bandwidth for various reasons, such as secure communication, resistance to interference, noise, and jamming. This summary introduces Direct Sequence Spread Spectrum (DSSS), Frequency Hopping Spread Spectrum (FHSS), Time Hopping, and h
